What is 4K? What is a 4K zoom lens?

The so-called 4K camera refers to the resolution of the camera to generate photos.


4k, generally refers to the video or photo files generated by the camera, the maximum single-sided pixels can reach more than 4000 pixels... This one-sided maximum pixel generally refers to the transverse pixel.


For a camera with a pixel value of 12 million, its photo resolution can reach the level of 4000X3000, so it has reached the requirement of 4k.



Some students will ask what is the meaning of 4K?

K is the first letter of the English word "kilo". It stands for thousand. 4K is 4000.

Then the maximum single pixel of 4K zoom lens can reach more than 4000 pixels. The following is the 4K zoom lens of pomeas.




Characteristic advantages of 4K zoom lens

POMEAS 4K wide field of view high resolution continuous zoom lens, not only has excellent zoom performance, but also provides a wider field of view, which can capture a wider range of images faster. It is an ideal choice for high-speed detection and accurate measurement applications. Compared with the traditional zoom system, the field of view is increased by more than 1.45X.


What is the current mainstream 4K resolution?

The general resolution of 3840 x 2160 and 4096 x 2160 pixels is 4k.



What is 4K resolution?

4K resolution is the trend of development, i. e. 4096 x 2160 pixel resolution, which is four times the resolution of 2K projector and HDTV, and belongs to ultra-high definition resolution. With this resolution, the viewer will be able to see every detail and close-up in the picture.


If the cinema uses an astonishing 4096 x 2160 pixels, no matter where in the cinema, the audience can clearly see every detail of the picture. The film is bright in color, clear and sharp in text, combined with super-real sound effect. This feeling is really an unutterable enjoyment.


In the field of digital technology, binary arithmetic is usually used, and the size of digital image is described by the pixels constituting the image. Because of the huge number of pixels constituting the digital image, it is usually expressed in K. The 10th power of 2 is 1024, so 1K = 2 ^ 10 = 1024, 2K = 2 ^ 11 = 2048, 4K = 2 ^ 12 = 4096.
